6 FAQs about [Intelligent dry self-healing capacitor]

Can a self-healing process destroy a capacitor?

Unfortunately, this mechanism can be dificult to control, and in the worst case, a run-away process can result, causing the destruction of the entire capacitor in short order. To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates.

Why should you choose a film capacitor with controlled self-healing?
